Error 23 when reactivating after windows update

Recommended Posts

Hi,

 

It seems like I'm having the same issue reactivating my Nitro Pro v12 that many people are. After windows updated Nitro showed as a trial version and when I try to reactivate I received error 23 license number already used.

I went to the deactivation website and deactivated my installs so it shows zero copies activated but I'm still getting the error.

Is this a behind the scene problem or could it be something on my end?

Hello @SWC,

Thank for sending me the serial number of your Nitro Pro.

To further assist you, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

Thank you for choosing Nitro and I hope this helps!

Hi, 

A similar problem happen to me. During my PC upgrade, I deactivated Nitro Pro without internet connection in old PC. 

After that, I cannot activate Nitro Pro in my new PC. 

Error 23 noted, again, again,....

I hope you could help me.

It seems that many users are having this issue. I am also trying to reinstall my V11 instance of PDFNitro and am getting error 23 saying there are no activations left for my SN. I have double checked on the portal and deactivated all of the installs but still cannot reactivate. Help!
